T 0 aZZ whomz't may concern:

j Be it known that I, ERASTUS EWV'INKLEY,

a citizen of the United States, residing-at Lynn, in the county of Essex and Stateof 5 Massachusetts, have invented certain new and useful Improvements in Heel-Building Machines; and I do hereby declare the following to be a full, clear, and exact description' of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to automatic heelbuilding machines, and it has speciahbut not exclusive, referenceto such machines as are adapted to buildpasted heels or heel- V blocks of tapered form frompolygonal lifts that are cut-from strips of leatherboard or other analogous sheet material.

Heret-ofore, whentapered heels have been manufactured,either by means of automatic heel-building machines or by the customary hand-processes,a series of graded lifts have been dinked out by means ofnumerous dies of the desired size and shape These dies are'difficult and expensive to make and to maintain in sharp working condition, and moreover involve a considerable expenditure 5 of money inasmuch as a large number of dies of diiferent'sizesand forms must be. kept in stock in order to meet the require v ments of various styles and sizes of shoes. 7

' It is an object of the present invention to produce an automaticheel-building machine which shall be relatively inexpensive to op crate and maintain by reason of theemp'loyment of simple straight cutting knives for producing lifts of polygonal form. such as areutilized in the method of building heels set forth in Patent No. 1,285,532, granted 40 November 19, 1918, on an application Serial No. 872,989,'filed November 19, 1914, by the present applicant, and which shall therefore obviate the disadvantages attendant upon the usual prior methods of manufacture;

Accordingly, one of the features of the present invention resides in an automatic heel-building machine in which plurality of strips of sheet'material are fed. to astraight cutting knife, or a plurality of such knives, which operates to concurrentlycut off a seriesrof graded polygonal lifts therefrom. These lifts are then coated withpaste, after which they are transferred to a" tapered and stepped heel-block.

positionv above an assembling table where-a traveling collector eflects their successive deposition and collection in theform of Other objects of the invention andfeatures by which they are attained will become apparent to those skilled in the art fromthe following description of the preferred embodiment of the invention illustrated in the accompanying drawings, in which Figure 1 isi'a vlew in front elevation of a machine constructed in accordance with the'rpresent invention; Fig. '2 is a view in side elevation of the machine shown in Fig; 1; Fig." 3' is a perspective view of-f'a heelblock whichis the resulting product of the machine; Fig. 4: is a perspective view of. a portion of a paste pot; Fig. 5 is a view, partially in section and partially in side elevation, of a clainping'd'evice for. securing the paste pot in: position ;v Fig. Sis a perspectiveview ofaportion-of a skeleton frame for supporting the lifts or pieces that are out from strips'that are fed from the magazines; Fi 7 is an enlarged view'in rear ele vatlon ofone end of the machine; Fig. 8 is an enlarged view, partially-in section, and

downwardly-projeating members 120 having screw-threaded bosses 122 integrallyassociated therewith. (lo-operating with. these bosses on each set of platesis an oppositely threadedbolt 124 thatis positioned midway between-itsends by a lug. 126 which jects laterally on the eenterdine of the ad- 58-andwhich is located between enlarged portions 127 provided on said bolt. .Simi

larly, the upper forward corners of the several plates 118 areprovided with bosses 122 (Fig, 7) and screw-threaded like construction.

'lhe-lorward. ends of themagazines are closed by a single plate 128 thatis provided bolts 124 of with a plurality: of upwardly projecting hooked members 130 (F igs. 7 and'1. 4)- that are located above the center-lines of the magazines and which partiallysurround the bolts 124 between theenlarged portions 127.; The various bolts 124, embodied in the mag azine construction just described, are employed for the -purpose of adjusting the spacing *ofqthe plates (118: of vthe several magazines whereby said magazines maybe adapted-to accommodate stacks of strips of any desired widths. I

. The lower portion of the. endplate-128 is provided with a plurality of vertically adjustable angl'e'members 132 (Fig. 14) that are bolted thereto and which severally carrya plurality of plates 134, the latter bei'ng 'lo-.

cated on thecenter-lines of the several=magazines for holding down the strips as "they are fed and for maintaining themunder control. ,Obviously, if heel-piles of tapering. forn1,:such as illustrated in Fig. 3, be.

built, the strips employed in the several magazines must be graded widths, and the adjustable magazines just described per- I mitofaccommodatingstacks of strips of any desired gradation s.

holding down plates 134 to the cutting knife 38 in'a series of steps bymeans ofthe strip.

pickers 32 (Figs. 2 and 14) which are se'verally disposed directly beneath eachof the 1 magazines and which are periodically recipe rocated to feed t-hestrips in the manner devided withk a, plurality vo't end prongs 136 (Fig. 12)" which areprojected into the low ermost strip in themagazine when the re ciprocating picker is advanced, whereby the sired. Eachof the'strip pickers 32 is prostrip is fed forwardly until it engages its. 1 i

stop or backgage As the strip picker is moved backward, the prongs are withdrawn from the, strip' a l, the strip is left in. proper position to be cut by the cutting knife 38; I I

The construction and operation of the strip pickers 32, the 'gages 34 and the detectors 361s similarto thatshown, described and claimed in Patent No. 1,352,492, granted cation Serial No.f143,738, filed January 22, 1917, by the present applicant, and therefore no; detailed description thereof is deemed September 14. 1920,.on a. co pendingrappli j necessary, reference being bad to said patent for. a full and complete descriptioniof the structure'andoperation of the appa ratus. V V v V Briefly, each strippicker 32 (Figs. 12 and 14) ispivotally mounted on a reciprocating carrier 138 which is suitablyisupported be neath the magazine table- 58 and is vactuated to and 71 1-0 by means of an arm 140 (Fig. 2) which is rotatively mounted, on a rockershaft 142 and which'is connected by ayielding coupling 144 to an"a rm 146 that is. fixed to the shaft 142. The shaft 142 is provided substantially at its middle with a fixed arm 148 that is. connected by means of a link 150with an ar1nz152 of a lever that is.

rotatively mounted on the rocker shaft 80 and is provided Withanother arm 154that carries. at its outerend a roll .156 that cooperativelyengages a cam path in the. face; of the cam 102; This cam 102 is designed Ina-smu'chas all of the strip pickers 32 are connected through the arms 146 to the .to'elfect the periodic oscillation of the shaft 1 .142 and the arms l46that are fixed thereto.

shaft 142m the manner just described, itis evident that all of the strippickers' are adapted to be actuated concurrentlyto effect the advanee ofthe lowermost strips in the severalimagazines. Thestrips are fed for.- wardly until their movement'is arrested by,

their engagement with the several rigid stops or back gages 34, whereupon ".sufiicient pressureas imposed upon the. yreldingcouplings .144 to effect their independent disconnection, so that, although the. operating arms- 146 continue to be actuated nofurther move ment of 'the strip pickers 32 is produced.

fl'lhe back gages or stops 34*constitute the e'ndsot 'a-series of levers 1 58 (Figs. 2, 11

and 14;), each of which extends rearwardly andis pivotally attached to an adjustable rack 160 which cooperates with a, pinion 162 that 111: turn engages a rack 164 associated -with an arm' 166, the end of which consti= tutes one of the detectors 86. IBy reason of the interposition of the'pinion .162 between the adjustable racks 160 and 164., thexpsition' of the back gage orstop 34 and the detector 36 may be concurrently and proportionately determined. The se'veral back gages o-rstops 3% are periodically raised into operativeposition'to perform-their intended functions by means of links 157 (Figs. 1, 2

' and 23) that are severally connected between the respective levers 158' and-a plurality of arms 159 tl at are fixed to a longitudinally disposed shaft-161. The shaft'16l7isconnectedto and operated by the cam 100 by means of an arm .16?) thatlhasalost-motion connection t'o-Ia bell-crank 165 carrying a roll that cooperatively engages the cam.

The purpose of each ofthe' detectors 36 is toper-iodically feel of tlie'strip that is being advanced to the cutting knife in order to determine its exhaustion or whether or not there is sufficientniaterial left in the strip sired dimensions. I In order to determine from which toocuta piece or lift of the de this fact, it is necessary that thedctector 36 be positioned a distance ahead of the cutting knife 38 which is equal to the distance at which the stop is placed beyond it,-as will be understood. Thus, if during the de- I detecting operations of the detector 36, it is found that the strip is exhausted or that it is so short that it has passed beyond the detector, theoperation of the strip picker 32 is so modified as tocauseitto engage and advance a new strip from the bottom of the stack. If, on the other hand, the'de tector Eiil-engages a portion on the strip during its .detecting operation in which case there is Cal sufficient material for a full. size lift to be cut,:the operation of the strippicker continues without modification and the picker acts intermittently upon the strip being ad vanced until said strip is usednp or is reduced'in length'to such an 'e Xtentthat another full size liftjcannot be out;

Since the construction and'operation of the back gages'or stops and detectors form no material part of the present invention and are described and illustrated in full in the above mentioned Patent No. 1,352,492, no further description thereof is deemed neces-' sary, except in so'far as the concurrent and V graduated adjustment of the detectors 36 and stops ("A is rendered possible through the agency'of an improved construction with which'the'present machine is provided, and

which will now be described.

In building tapered heel-piles or blocks; l I as illustrated in .3, it is clear-that the lifts'of which they are composed are graded component; lift.

in width as wen as a. length; I The. aar

lengths of the lifts that. are produced from the strips in the.variousmagazines aredetermined by the widths of the strips themselves, but the Width of the lifts out therefrom are determined by the extent to which the strips are advanced during their feeding movement, which in turn is fixed by the positions of -t heseveral stops or back gages 34. It isnecessary therefore to adjust or; set those stops or gages 3% in: accordance lifts of the desired graded widths shall be out from several stripsv In orderto effect.this adjustment of all the stops 34 by a single operation, each of the racks 160 at the respective ends of the machine is provided with a bracket 170 into which is screw threaded an adjusting rod 172 (Figgll) that projects through a'suitable opening inthe rear frame member 62 and is provided Witha knurled head 173 by 7 means of which it -isadjusted to vary the position of the associated rack 160 and; therefore, of the stop 3% and detector 36 connected thereto. A bar 174 is connec'tedby means of bolts 176 and nuts 17 8 to each of the adjus'ty able racks 160 whereby all of the stops and detectors are interconnected and correlated. To concurrently andproportionately set the gages 84 and the associated detectors 36 for building a tapered heel-block'of any de sired pitch or formation, is therefore only necessary to adjust the two end racks 160,

by means ofthe adjusting rods 172, so that; the distance A fro-1n theend of one 'ofthe end/racks 160 to the rear finished face 180 of the frame member 62 shall be equal to the desired width of the largest lift in the heel t0 bev built and sothat the corresponding dis-1' tanc'e at the other end of the machine shall too be equal to'the desired'width' of the smallest mediate stops 34" and detectors 363will be 7 Having effected this ad- 7 justment in the-manner described. the 1111361".

properly and proportionately'r adjusted,by reason of the interconnecting bar 174 3 so as to insure the cutting of aseries of lifts of proper graduated widthsxto produce a heel blockz ofthe desired form and pitch;

I The cutti'ng knife 38 which concurrently cuts lifts of graded sizes from the several strips that are fed into position against the respective stopsv or back gages 34' is reciprocatedperiodically during theioperation of;

the machine; The knife 38' is'of ordinary form and conven ently comprises a plurality of sections, as shown'iin'Figfl, which re" secured to a reciprocablebeam 184tby' means of bolts 185. The "beam 184: 1 slidably rality of hexagonal posts 188" (Figs. 2, 9' and 10) which are set mto the upper ends,

mountedat its respective ends upon a plu- -wardly beyond the guide posts186 and respectively carry pins-192 to whiclrsubstantially vertical ope-rating rods 194 are pivot ally connected (Figs. 2: and 9) The operating rodsltla are disposed outside the re- V spectiveside frames 54; and" 56' and their lower ends are pivotally connected to crank -pins 1 96-th'at arecarried by the eccentrics 110 which are secured tofthe respectlve ends of the'cam shaft 78'.

From the foregoing description, "it is manifest that, as the cam shaft '7 8 is continuously rotatechthe bea1n'186 and the associated cutting knife 38 are periodically reciprocated to cut liftsof predetermined dime'nsionsfrom thestri'ps' that are inter- Qmittently fedinto cutting position against the stops e I As the knife 38 descends lnt-o its-cutting positlon to sever a row of lifts from the strips, it cooperates with the'cuttingblock" 68 (Fig. liwhich'is supported in position beneath it on the cross brace 64 by means of a 'c'lainping'member 200 and a plurality of bolts'202. 2 i

The reciprocating beam 184: carries a plurality'of' springcushioned ejecting pins 203 which, in the lowered position of thelmife,

project through openings 205 in theholding down plates into engagement with-the "strips. 'If the strips are suiiiciently long to besupported upon the detectors 36, said ejecting. pins yield'upwardly against their springs, but if 'any strip is too short for anotherfullsized lift, the pin pushes the remnant end thereof-downwardly and effects its ejection. r f Having cut a row of lifts from the strips, said lifts are'transferred across the slotted plate or tab'le 66 and in position upon the skeleton supporting frames by means of.

- receive a rod 20'8tha t extends longitudinally of the machine andupon which the end members 2O l'rest. The other e-ndsofithe' end members 204: are provided with extending fingers 210- that normally, are" adapted to rest upon theupper edge of the plate 66,

,Between the end members20 t of therespective'frames are a plurality of parallel members 212 which arec0nvergently disposed in an upward directionfand across' -which a plurality {of members or-wires 214are secured by means of screws 216. These wires servejthe purpose-of-supporting the lifts which are transferred thereto by means of the lift pickers-42. i I The lift pickers 42 are of like construction,..and each embodies a substantially horizontal arm 220 (Figs. 2, 14: and 17) to the forward end of which'a substantially ver tioalplate 222 isisuitably secured; -This plate, 222 is provided with a plurality of downwardly projecting prongs 224: Iwhioh 1 constitute the picker points for seizing the lifts that are: cut from the strips of sheet material, and which rest upon the plate 66. A presser foot or stripper 226 is mounted upon a movable'pin 228 adjacent the end of the arm 220 and is normally maintained in its lowermost position by means of a spring 230' that surrounds said pin. During the normal operation of the lift pickers 42, said pickers are swung to the right, frointhe position shown in Fig. 17,, until the downwardly pro ecting prongs of the pickers are in position over the lifts that have just been'severed from the strips of sheet material. During this swinging move.- mentthe arms 220 are tilted in such-a manner as to force the prongs downwardly into the lifts, whereby said lifts. are laimpaled thereon, the presser feet 226 being thereby forced upwardly against the action of the s rings 230 as illustrated. in Fig. 14L. Q The transferringreturn movement of the lift piche-rs'then takes place during which the pickers are concurrentlydrawn in the opposite (lllQCtl'OlTuIitll the several lifts are in position upon the wires 2l4l-ofthesupportingframes 4:0. Thereupon, the arms 220 are tilted so as toraise'the picker prongs 224to permit the strippers 226 to be pressed downwardly to strip or remove the lifts therefrom, whereby said lifts are deposited upon the supporting frames. The return movement of the pickers then continues until said pickers are. withdrawn to the left of the supporting frames,as shown in Fig.

This cycle of operationis effected by means of the cooperative action of the two cams 94 and the cam 106 (Figs. 1, 2 and 23) that are fixedv to the cam shaft 7 8, through the operating mechanisms now to be described. Since there are two duplicate sets of operating mechanisms, one for each'cam 94, adesoriptioirof onlyv one of them will be given. 7

' Traveling in the cam path of the cam 94 atthe right hand and of the machine (Fig. 1) is a roller 232'which-is. carried at the end ofan arm of a bell-crank 284 that is rotatably mounted upon the rocker shaft 80. The

other arm of the bell-crank284 is connected to a link'236 '(Fig. 2) which has a pivotal connection to one armof a bell crank 288. Said bell-crankis mounted upon aflongitudinal shaft 240; carried in the side frames 54and 56 and its other arm hasfa pivotalv connection with a link-242; The upper end of the link 242 is pivoted to one end of an arm 244 which is pinned to the inner end of Jastud 246 carried by the frame 54,; and is provided with anotherdepending arm 248 fixed to the other-end thereof. The lower end of the arm 248 is, connected to the lower end ofa bell-crank 250*by means of a link,

252, and ,said-bell-crank' 250 is. pivotally mounted upon a pin 254that is carried by.

frames- 54 and 56. p The shaft278 serves tov support and carry all of the picker arms 220 which are fixed thereto 17). v n

. The mechanisms at the respective ends of the machine, just described, serve to effect rotative movements- 'of' the shaft 278 and, therefore, the desired tilting of. the picker by'keys 221 ig.

arms 220, which are keyed thereto, whereby the picker prongs areraised and lowered in 1 "position at the proper times as determined by the cams 94.

The swinging movements of the picker.

arms 220 are effected through the agency of the cam106 which cooperates with a roller 260 (Figs. 2 and 28) that is carried 54 and 56.

by one. arm'of a ibellcrank 262 which is rotatably 'mounted upon a rocker shaft 80.

The other arm of the bell crank 262 is connected by means of acoimecting rod 264 with an arm 266 that is fixedly mounted uponthe longitudinal shaft 240, and the respective-ends of said shaft are connected tovthe lower ends of rods orlinks; 268 by means of arms 269 that are secured thereto. The upper'ends of the rods 268 have pivotal connections-to arms 270 that are severally fixed to the inner ends of studs 27 that are rotatably'mounted upon the frames Other arms 274'fizred' to the outer ends of the studs 272. are pivotally associated at 275 with levers 276 inter;- mediate their ends. The lower-ends of the levers 276 have pivotal connections with pins 254 that connect the bell cranks 250 with the arms 256', while the upper ends of the-levers 276 are pivotally associated with the respective ends of the" longitudinal shaft 278 to which the picker warms 220 are keyed,

a This portion ofthe operating mechanism serves to swingithe shaft 278 and its a's 7 in Figs. 2 and14, and theirfforward 'posi tions, as indicated'in Fig. 17.

u From the, foregoing 7 description it is evident that the operating mechanisms associated with the cams 94 and 106 are respectively adapted to'efi'ect thetilting and swinging movements of the I picker arms whereby the row of lifts that are cut from the SEYGlillStllPS are seized, transferred to the supporting frames '40 and subsequently deposited thereon. .7 I

inasmuch as the: present machine .lS intended to build'pasted heels, provision is" made toapply paste to all-but the bottom lifts thereof. This is accomplished through the agency of the pasting apparatus 46 which is disposed beneath the skeleton frames 40 for supporting the lifts after they have been cut and transferred thereto.

The pasting apparatus is operated in such manner as to coat with paste the bottom surfaces of, the lifts resting upon the wires 214 of the supporting frames 40 and to subsequently raise the frames and the lifts rest,-

lifts may be seized by the lift carrier' '44 when it occupies its receiving position, as

mg thereon into I such position that the tudinally of the machine in end-to-end relation and beneath the supporting frames 40 A plurality of paste pots areemployed in lieu of a single one merely for purposes of convenience in removing them to be cleaned. The paste-pots 282 and 284are detachably, ,mounted in a manner to'be setforth upon-a movable supporting frame'286 which is carried by a plurality of operating rods 288.

that project loosely through suitable guide openings in the cross brace 70. The lower ends of the operating rods 288 are. pivotally connected by means ofpins 290 (Figs. 2 and 28) to the upper ends of a-plu rality of links 292, the lower ends of which are'provided with elongated slots 2 94which are adapted to receive the respective crank pins 296 that are carried by crank arms 298 secured to the opposite ends of the auxiliary shafts 82 and 84. As the shafts 82 and 84 are, continuously rotated in the manner already set forth, the crank pins 296 cooperate, through the pin-and-slot lOSt-HIO- tion connections just described, to effect the periodic reciprocation of the movable supporting frame 286 and the paste pots mounted thereon. The provision of the. pin- Being, of like construction, a de and-slot lost-motion f connections is for the V purpose permitting the paste pots 282 and 284 and the supportingiframe 286 to temporarily rest upon the supporting and I guiding. cross-brace 70 when the paste pots occupy their lowered positions,"as will be understood. l scrlption v of asingle paste potwill sufiice. Thef paste pot-284 (Figs. 4, and 14-) is of rectangular trough-like Construction and it's base 302 islarovided with suitable'outer groores to receive inwardly projecting guide. members- 304tliat are associated with the movable supporting frame Thus; a dove-tail way COilStitiCtlOH is provided wh ch permits ;-the paste pot to be slid intoand out of v positionlongitudinally. V For the purpose of 7 between the base portion firmly securing the paste pot to the support ing trame 236, a gioor bar 306- is provided 302 of the paste pot and the adjacent portion of the supporting member 286, and this gib is clamped tightly against the base portion-302 by means 'ota plurality of clamping bolts 3(i=8 which-are provided with laterally pro ecting'pins310 for convenient manipulation."

In'order to apply paste to the under surfaces of'the lit'ts resting upon thesupporting "wires 214 of the frames.40,-the paste potis provided with a plurality of paste applying plates 312. These plates,

with the exception of the one at the right hand end of the machine which ,acts upon the first or botto m liftfof the heel, are rotativelyv mounted in such manner as to be periodically immersed in the paste within thepaste'pot. Each of the paste applying plates 312 is provided with side lugs 314 that are pinned'tto a supporting rod 316which projects laterally across the paste pot and .has its hearings in the sides therehe rod 316 of the right-hand paste. applying plate 312 is fixed in position so "that the plate'is always maintained inits raised position as indicated in Figs. 4 and r 18, and therefore is never immersedin the paste. Hence, the right-hand lift, y-which' later constitutes the base-lift of thefheel is not coatedon its underside." I i The rods 3116 upon ,which" the remaining paste applyin 'plates 312 are secured are rotatively mounted in thesides ofthepaste pot and oneend of each rod isprovided I with a pinion 318.v These pinions 318 mesh with a slidable rack 320iwhich moves 'longi tudinally in a groove provided 1n a projection 322*exte1'1ding laterally from one side of the paste pot. A cover 324 envelopes the pinions and rackand protects them from inury. v

In order to effect the longitudinal reciprocation of the rack-320, the laterally projecting member 322 is slotted throughout a considerable portion of its length to permit the movement ot a slotted yoke 326 which projects downwardly through the slot in the member 322 andis secured tojsubstantially 1' the middleof therack (Figs 4 and 16). i The lowenend ofthe'yoke 326 projects below the member 322 into such position thatfthe extends into the, slot thereof; Thez--pin330 is" provided with a -.;knurled head .334 by means; of Y which the pin may be screwed into and out ofengagement with the -yoke 326.

A check nut, 336" is also provided; for look- .ing the pin in its-adjusted position!

The'opposite end of the stud 338 isprovided with. an arm 340 to the end of which a-link 342 is con,- nected. The'lower: endcof the link 342 is associated with an. arm 344 (Fig.1 23) of abell crank byrme'ans of a universal connection 346.- This bell crank is rotatively mounted on the rockershaft 80 and its other arm-347 isprovided with a roll 348 that engages a cam path on the 021111104 v The cams-i104 are-designed to eifectthe periodic reciprocations lofithe racks 320 endof a threaded pin 330 (Fig; 8) that a 3:

A already stated, they elevation of the paste pots effect-s the disengagement ofthe1pins 330 from the slotted yoke members 326 by means ofwhich the racks are reciprocated.

When thistakes place, the respective cams 104 serve tofnia'intan theoperating levers 332 carrying thepins 330 in vertical position in order that they maybe ready to again effect the operative connections be tween the pins 330 and the yoke- -members 326, when the paste; pots are lowered.

It is necessary, 'however, to provide means for locking the paste applying plates 312 in their horizontal position during this movement i'norder that they shall properly engage and applypaste to the'under sides of the lifts resting upon the wires'214 of 7' ried' at the end of a lever 354 that is pivotally mounted upon a pin 356 supported in a bracket 358 that is attached to the side of a paste pot. The other end of the lever; 354 is normally maintained in engagement with an .adjustable set screw 360 by means ofa spring 362 that is positioned between st 366 which is carried by the stationary' in their lowered position. I

said lever and. a block 364 that is fastened to the side of the paste pot. Theset screw 360 is adj ustably mounted in a central bra-ck? crossbrace 70. With this constructioin the- .various parts of the lockingdevice, just deseribed,.occupy their released positions, as slidwn in Fig. 16,. when the paste pots are As soon as the paste pots are raised, however, the freeends'of 'the levers 3541are disfat engaged from the set screws 360 and the springs 362 serve to force "the locking. pins 352upwardly and into the openings" 350 in the respective racks. Tlrerefore ,j the rotatable past-e'applying plates 312 are positively i retained in horizontal positionwhile the;

paste potsare raised. 1; H V 1 Upon the loweringof the paste pots, the set screws 360 engage the levers 354, therei by overcoming the springs 362 and withbeen immersed inthe paste are brought into engagement with the wires 214 of the support1ngframes'40, andwith the under surfacesof the lifts disposed thereon, asindicated inv Fig. 17, the plates312 being provided with a series of grooves 370 which are adapted to receive the wires 214. As the elevation of the paste pots continues,

7 the supporting frames40, together with the lifts resting thereon,-are raised into the position indicated in dotted l'inesin Fig. 17, in which position the lifts are seized by the lift carrier 44 in a manner'to be hereinafterdescribed. I j

- .By reason of the construction of the supporting frames 40 and their method of support, said frames are raised bodily from the, supportingrod 208 and the plate'66 up{ on which the ends thereof respectively rest; As the paste pots arelowered subsequent to the seizingof the lifts by-the lift'carrier 44,

the supporting frames 40 are also lowered until they again rest upon the supporting rod 208 and plate 66. In order to guide the supporting frames into proper positions when they are deposited, as just described,ia plurality of guide members. 374 (Figs. 16 and 21) are located upon the rod 208 at the respective ends of "the two supporting frames. These guide members 374 are provid-ed with curved surfaces 376 with which the end'members, 204 of the frames are adapted to copperate and which function to definitely determine the position of the frames. i

The lift carrier 44 which seizes the lifts,

when raised in the manner just described, comprises a plurality of complemental channel members 378 and 380 (Figs. 1, 15 and 19) which extend the hill length of 'tl1"e' machine and which are secured at spacedin I tervals toa plurality of spacingmembers' 382 18). The carrier frame, thus formed, is provided with a plurality of spaced pickers suchvas' shown in. Figs. 15-

and 19. These pickers are located in aline HIBIltWltl'l theseveralmagazines so that they are properly positioned to seizethe I several lifts that are raised by meansofthe reciprocating paste pots.

these pickers comprises a rod 388 thatis slidably mounted iii-vertical position inthe channel members 37 8 and 380 comprising the carrier frame. The lower endofieach rod 388 is provided with. a stripper plate "390 havingopenings 392 therein to permit the passage of acorresponding' number of picker prongs in, the form of pointed mem hers 3941113011 which the lifts are impaled through it the action of the reciprocating paste pots.

A coil spring 398 surrounds the, upper end of the rod 388 and'acts against the-collar 396 to normally maintain the rod and its associated stripper platei390 in its lowermost position.

The picker prongs 394 are suitablyysecured to apla-t'e 400 which is fastened to the lower surface of" the lower. channel member 378 by meansof screws 402. The plate 400 isalsogprovided with an upwardly entend- 'ing'portion 404(Figs., 18 and 20) which is disposed against the front face of the lower channel member 378 and is fastened there- .to by means of screws 406. The plate40 0 is provided at its frear corners with notches,

(Fig. 20) to accommodate thescrews 402,

and at substantially the middle of' its rear portion it is provided with a recess 408 to permitthepassageof the rod 388; A tongue member 410 projects rearwfardly from the plate 400 and into arzslot 412 that is provided in the rod 388 whereby said rod is prevented from turning although. permitted to be raised and lowered in position.

lVhen a lift is raised and impaled upon the picker prongs 394'by the elevation of the past-e pots, thestripper plate390 is forced upwardly against the action of the spring the channel member 378 and is provided with a trip member 422 (Figs. 15, 18 andpinned thereto, by means of'which the latch 414 is subsequently released to permit the spring 398 to force the stripper plate 390 downwardly and thus strip off and discharge the lift seized or impaledby the picker prongs.

tDuring the operation of the machine, the

lift carrier 44 with its several associated; picker members is swung froma receiving position, shown in Fig. 15, in which the several lifts are seized, to a delivery ost tion, shown in Fig. 2, in which the lift car-' rier is located above a portion of the assembling table 48 and in which position the lifts are released and deposited upon the table in a manner to be herein afterdescribed.

In order to effect this swinging movement.

of the lift carrier and to maintain it in vertical position throughout its actuatioinfa parallel-motion :uechanis'inis employed and i will now be set forth. Referring particularly to Figs. 2 and-18, the lift carrier, frame I is pivotally mounted at ltS'IGSPGClZlVE ends.

upon the corresponding arms 426 of a pair of similar three-armed levers that are respectively pivotally mounted upon studs 428 which are carried by brackets 430 constituting parts of the several binding braces 188' which serve to hold the hexagonalguide' posts 186 in position. Another arm'4'82 of each of the three-armed levers, just referred to, is connected to one end of an arm 434' of a bell-crank by means of a link 436; This bell crank is 'rotatively mounted on a'pin 438 carried by a bracket 430 and its other upwardly projecting lug to the carrier frame.

The lengths of the arms 426 and 440 and the locations of the pivotal connections 444 that is secured thereof with the carrier frame and-with the,

bracket 430 are such that a parallel-motion mechanism is provided Which-insures that the lift carrier and its associated pickers maintained in a vertical position" throughout its movement. r t f Each of the three-armed levers, already referredto, embodies a third arm 446 which is connected by means of a link 450' to one arm'of a; bellcrank 452, theother arm-of which has, a p v t ltoeiiect ca with the upper end of a connecting rod 454. The

lower end of the connecting rod-454 is pivotally associatedwith an arm-456 that is fixed to the rocker shaft 80. v

' The rocker shaft 80 is periodically rotated through the agency of an arm 458' (Figs. 1 and 23) that is fixed thereto at substantially the middle thereof and which carries at its outer end a roll 460 that co-operativelyengages a campath in the cam 98. The cam 98 is designed to effect periodic rotative movements of the rocker shaft 80 whereby the lift carrier 44 is swungfrom-one of its operation of described.

The lift carrier 44 is definitely located in the actuating 'inechanisins ust :operative positions to the otherthrough the 5 its receiving position by means of a plurality of notched stop arms 459 (Figs, 15 and 17 that project forwardly from a supporting channel inen'iber 461 that extends. longitudinally of the machine and is secured to the upright pedestal members 1960f the" respective side frames] These stop arms 459 are. engaged by position-limiting rods 462 that are mounted between brackets 463 which project upwardly from the up- I channel member 380 of the carrier frame.
